Is 195 a deficient number?

Here we will explain and calculate if 195 is a deficient number and its deficiency if applicable.

195 is a deficient number if the sum of its proper divisors is less than 195.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 13 + 15 + 39 + 65 = 141.

141 is less than 195. Therefore, 195 is a deficient number.

The deficiency of 195 is 195 minus the sum of its proper divisors. Thus, the deficiency of 195 is 195 - 141 = 54
